3L Duramax Sierra (almost) 75K Mile Review

It's been a looooong time since I posted on this. 2023 was a rough year for me personally and professionally, but it's a new year and things are getting better.
We're around the 75K mile mark on the '21 and I give my not-so-concise thoughts on my 3L Duramax. Am I still in love with her??? Watch to find out!

[@dopeboyp3487]

Sorry about your dad man… I lost mine in 2013 to cancer. Most of the time I’m ok, but every now and then I still get choked up reminiscing about him… Especially when I see his face in the mirror, or when looking at my sons. Rest in heaven, and may God bless your family going forward. On a lighter note, nice truck brother… I take delivery of mine April 24. 👊🏽💯

[@dukeofwails]

I came here because I just bought a Sierra with the same engine. But what I really found out is that you seem to be a really good down to earth. I am so sorry to hear about your father. It’s clear that you loved him. I’ll be saying a prayer tonight for you guys.Thank you for being transparent. That’s what built a community.

[@donison-xu3qf]

Came for the truck review, stayed for the guy who made the video. I'm sure you'r old man would be proud. subbed.

[@impala-wf2sd]

I have a 2021 crewcab Z71 RST 3.0 4x4 standard bed. I paid 52k for it & average 700 miles to a tank (highway miles) per week. I'm at 46k miles & have had zero issues so far. Lm2 is not burning oil & low end torque is amazing. Oil pump belt change is at 200k (revised) . I would recommend this baby duramax to anyone in the market for a full size truck with 30 mpg +. I love my truck & have zero regrets. Haters will continue to hate........ just smile.... sorry for your loss Dave 🙏🏾🙏🏾🙏🏾🙏🏾🙏🏾

[@davidcerce]

I have a 2023 Denali with the LZ0. They have addressed what they learned from experience with the LM2. This is the most refined drivetrain I have ever owned! I’m 68 and I’ve been buying new vehicles since the 80’s. My last vehicle was a 2020 ZL1. Yes, I’m usually buying gm. I get 23 mpg around town and I live in the mountains. Believe me it’s the smoothest and most refined power delivery I’ve ever seen!

[@chaseydog7956]

Picked up a 24 AT4 Duramax last week. My first diesel. Appreciate the videos on your experiences with the truck and engine.

[@adamy9260]

Sorry about your dad Dave. Glad to see you back posting videos on the truck, been long overdue ;)

Sorry for your loss brother. I don’t know you, but I can see that your father rise an awesome man. ❤

Keep trucking brother! Your dad would be proud of how you are taking care of your mom ! Thanks for the review

[@michaelgoodwin142]

Sorry to hear about your father! Your review is very solid though. You weren’t trying to sell anything, just giving thoughts and opinions. Keep up the great videos

[@chasingthedream4390]

Sorry for your loss. I didn’t want to sell my truck either. And was is the same situation where we needed a family car, what I did was found a decent 04’ suburban and it worked out great for those couple times we need it. Plus I was able to remove the back seats and keep things locked in it when going fishing and things like that. Just my 2 cents anyways.

[@kylebenich8441]

Condolences for your dad...glad to see you back.

[@BforVendetta6]

The way he optioned out this truck is perfect for what I personally like.

[@UntoDeath]

Sorry to hear about your father. I’m glad you’re doing better and taking care of business. Appreciate the review. I think I’m going to grab one of these.

[@Podchynok]

Sorry for your loss, I hope your dad lived a long life and took a lot of memories with him. This past winter we had -43C, Canada eh, got up in the morning to go work out with my buddy. My 2021 GMC 3500 6.6 gas did not start, but guess what, my wife’s 2023 Tahoe 3L diesel did, I was shocked.

I'm sorry about your Dad. I enjoy your videos and approach to it all (have the same truck). You influenced my decision to buy mine. Be well.

[@chazman4461]

Very sorry to hear about your dad. It took me a long time to recover from loosing my dad. It is pretty awesome you can go so long between fillups. The tundra hybrid does not even get that kind of fuel mileage per their window sticker.

Glad you’re doing ok brother 🙏

[@kevinmackkk]

21 Sierra AT4 here with the 3.0 duramax. Currently only 35,000 km on the truck and for the last 4 months it has been nothing but problems. ECM has been replaced(1 month back order on parts) then within 20 km the injectors failed and needed to be replaced. Currenty it's back in the shop with a diagnosed failed turbocharger, once again no stock inventory of them. Have loved the truck but worried about the reliability factor due to living a very remote location well away from any dealer.

[@nahbro3240]

I think is more about the control quality on parts then the truck itself. If you could see how people doesnt give a F today. They building truck for 20$/h that they will never be able to buy😂.

[@donmckenzie5027]

Great video and I am sorry for your loss!

[@lesphilaja5722]

Sorry about the loss of your Dad. Mine left me in 2020, I think of him daily. My 21' RST has just South of 25K. My dealer is trying to get me to trade up to a 24'. I'm being offered just about what I paid as trade-in value. 24' is stickered at close to $60K. The 21' 3.0 cost $995 additional. 24' is now somehing like $2600 additional.

[@BanditDavesToyChest]

Yikes

[@edwardpate6128]

I have been getting the same sort of offers on my 2022 GMC SLT. It has been a great truck so no interest in that as I'm retiring in 2 months.

The LM0 diesel option for the 1500’s still shows as a $995 option when I did build and price for a 24 Silverado.

[@GreenLabLawncare]

I appreciate your video. Looking to buy a truck to use as a truck. Looking at this, an 5.0 F150 or V8 tundra

Congrats for that milestone .. Just asking did you run any diesel additives to your dmax?

[@BanditDavesToyChest]

Zero point zero additives…

[@nomad_R1]

Loved this video. Right there with you.. my wife has a 2018 Jeep wrangler and my F250 (6.2L) is the “family” vehicle but hoping to get our hands on a Yukon or Suburban 3.0L to replace my truck.

[@BanditDavesToyChest]

Good luck brother and if you stumble on a good deal, let me know about it! Everything I’ve looked at so far (albeit casually looking) has been too rich for my blood.

[@GrowinwithAJ]

i just traded mine and after lossing 20 thousand dollars from my down payment i still feel a relief . i asked chevy to do a buy back and the dealership wouldnt offer me my money back. i want to be clear it never drove or ran right and was always in the shop. i have bought nothing but chevy for 20 plus years ill never buy another one and as for diesel it will have to be deleted. my wife wanted a tahoe and after this we bought the jeep grand wagoner and i traded for a gladiator and couldnt be happier. 3.0 has been nothing but problems for so many folks i wanted it to work but it sucks and chevy disapointed me. i used my VA disablity money on my forever truck and now im back to square 1. all my accesories dont fit lost over 25000 dollars

[@mauriciocastro6363]

Sorry to hear your bad experience. My 3.0 diesel has been performing great. No issues at all. My wife's best friend has a 2019 Silverado RS that had oil pan corrosion issues. They had to replace it 2 times. What kind of issues did you have?

[@GrowinwithAJ]

@@mauriciocastro6363 i had viberation issues the trans and torgue converter and pumps where replaced 2 times and def system 2 times during winter months the exhaust would choke you out of the cab and it smelt like electrical fire after a long drive or tow. motor shut down 2 times but never repeated. there was so much wrong with that truck

Sure do I will be posting up a vid on it shortly and will give you all the info as soon as I get home. Thanks for watching!!!

[@richardhawes5156]

I bought a 2023 3.0 Silverado. I've been driving it very conservatively. The best mileage I have been able to get is 29. Usually with the cruise set at 76 on the Freeway I'll get 25ish. Truck has 3500 miles so far. What am I doing wrong. Why can't I get consistent upper 20s on Freeway drives?

[@randyatcitty8369]

I wish GM can build a diesel 3.0 without chains and belts in an engine , if so I would for sure buy one .

[@mauriciocastro6363]

Thank you for keeping the reviews going, I have the same truck but I'm at 27k miles in 2 years, so you are a good reference to see potential issues. Did you evere replace the shock absorvers? I have the X-31 package and I'm not happy with the Ranchos, the truck is excessively bumpy, bounces a lot on little bumbs on the road, and it gets unstable in no time. I'm willing to put the Bilstein schicks.

[@paulbenderavich3833]

Rancho are junk. Switch to Bilstein.

[@voltron2127]

Yes, switch to Bilstein. Best thing I ever did for my 2022 GMC Sierra 1500 3.0 Diesel 4x4. Night and day difference.

I am a new subscriber have test drove a couple 3.0 litter durmax trucks, and would like to say I am sorry for your loss of your Dad. I was wondering have you had oil consumption issue on your truck. By the way I looked at a GMC Denalli loaded but vehicle was over 70,000 hard to buy at that price. Love your youtube channel you say things like they are. Thanks again Happy New Year!

[@jaskarnnehil4193]

just bought a 23 silverado rst with the 3.0 LZ0, a little over 3k miles and see no oil consumption. I have mainly seen this issue in the previous gen motor, the LM2.

[@akamanonthemoon]

Looking for new truck as my 2019 Ford Ranger with 60,000 had transmission go out and need overhauled spending 13 weeks at Ford doing so!! I was going to go back to a Toyota Tacoma or Nissan Frontier till couple of friends purchased GMC ATX4 with mini diesel and heard the gas mileage they were getting. But man the price is a killer!! Looking at maybe a used one couple years old with 20-30,000 miles. They are nice though!!

[@BanditDavesToyChest]

The prices across the board have been ridiculous. I wanted to lateral into a Yukon or XL and it was a huge increase in price I couldn’t justify

One thing that irritates me is on my 24 i lost 4low because it has the max tow package.

[@gavincopple9206]

are you running 0w20? how many miles between oil changes?

[@BanditDavesToyChest]

Yep predominantly Mobil 1 esp x2 since autozone generally has it in stock. I’d say ~5 to 7k miles. Just go with the oil life monitor.

[@toddbunnett640]

What oil do you run? I know in one of your videos you quit using the dexos d stuff. My 2021 will burn at least a quart of ac delco stuff when I’m about 30 percent oil life left. When I use valvoline I don’t get any burn off. I’m at 100 000 kilometres on mine and my trucks been all over. But no major complaints. First 25000 or so I had the no start long crank issue. At least once a week. Got videos of it. Dealer wouldn’t touch it. Then I had the charge air cooler replaced under warranty at 40000 and then again at 100000. Same thing twice. My engine temp also runs all over the place, never sits at one temp. A change from city driving to the highway the needle will creep up 3/4 way to red line for about 10 mins then crawl back to the middle.

[@BanditDavesToyChest]

0-20 esp-x2 for the oil. Easy to get now. No real issues here.

[@16vjohnny]

Spring knock? Are you talking about your leaf springs? There’s a shackle that goes around the leafs on my 22 Silverado. Spray some WD-40 on them and I’ll bet you the knock goes away. Just something about that metal shackle with the plastic bushing.

use a 6 point socket on your fuel filter and it will never strip
